LEAKAGE TESTS
1. Build the air system pressure to governor cut-out. With
the dash mounted trailer supply valve activated for
tractor/trailer operation, apply a soap solution to both
exhaust ports (one in cover and one in body). The
leakage noted should not exceed a 1" bubble in less
than 3 seconds at either exhaust port.
2. Make and hold a full brake application and apply a soap
solution to both exhaust ports and around the cover
where it joins the body. The leakage noted should not
exceed a 1" bubble in less than 3 seconds at any exhaust
port with no leakage detected between the cover and
